A human body built in with various types of cells. Fundamental unit of life in a human body is cell. A matured human body is made up trillion of cells and depend on body environment to live and function. Cells, tissues and organs perform a different function in the body. To maintain a constant internal environment for well being, individual cells of the body required three important component oxygen, nutrients and removal of waste. Process in the body controls its internal environment is called homeostasis. This process is essential for the human body to survive. According to Oxford Dictionary, homeostasis defines as the tendency towards a relatively stable equilibrium state between interdependent elements especially as maintained by a physiological …show more content…

Human body made of a combination system which able to work throughout the body and maintain a range of the body function where required cells to function. All the body system works together to maintain body function, but various systems such as nervous, digestive and endocrine systems have specific roles in homeostasis. It is related to homeostasis and actions coordinated by the hypothalamus. It is a process where the body takes part to keep the internal environment of the body at equilibrium state where can detect the changes in the external or internal environment of body. Hormones work in the body to regulate the activity of body cells where it relates to homeostasis as the presence allows the effective function of hormone in the body. The mechanism depends on action and interaction of several systems of the body. Factors that affect the ability body to work efficiently include temperature, acidity or concentration of nutrient. This allows bodies to operate efficiently without any harm being caused in the body. Therefore the presence of homeostasis in the body is highly necessary and …show more content…

In the regulation of blood pressure baroreceptor is the receptors and the medulla oblongata is the control centre while cardiovascular system is the effectors in the regulation blood pressure. When heart rate increase in a human body, more blood will pump into the arteries and will result in increasing in the blood pressure. This event detects by baroreceptors in the arteries wall and receptors will send impulses to the control centre known as medulla oblongata. Medulla oblongata will interpret the message and send the message to the effectors in body cardiovascular system. Thus it will slow the pulse and decrease the blood

Even though we cannot see cells without a microscope, they are the basic unit of life and they exhibit all of the characteristics of living organisms. They can exist individually, as do bacteria, or they may work together, taking on specialized tasks to create a more complex organism. However, all living organisms share certain characteristics, which are discussed below. Cells are made of cytoplasm.

According to Martini, F., Tallitsch, R., Nath, J., (2018), the ANS functions outside of our conscious awareness and makes routine adjustments in our body’s systems (Martini, Tallitsch, & Nath, 2018, p. 450). The autonomic nervous system helps maintain the homeostasis of our bodies by regulating body temperature and coordinating cardiovascular, repertory, digestive, excretory, and reproductive functions. Efferent axons innervate the visceral organs and the efferent nerve fibers and ganglia of the ANS organize in two systems or divisions. The sympathetic division and the parasympathetic division. The sympathetic division is most active during times of stress, exertion, or emergency, also known as “flight or fight”.

To begin, the integumentary system also known as the skin, is the part of the body that meets the air. The skin is the largest organ in the body that comprises 15% of body weight. The skin has various functions, which are to regulate temperature, sensory perception, blood pressure control, excretory, and etc. One major function of the skin is to protect. The skin is the protective covering of the body that prevents the invasion of microorganisms.

There are some messages that travel on a pathway of nerves until they reach your spinal cord then brain. This process allows your body to react to things instantaneously. There are 12 important systems in the body, the nervous system being one of the major ones as it controls all your functions connected to all your vital organs and muscles. In 1906 British physiologist Charles Sherrington published a book describing how the nervous system works, thus giving people a better understanding of the functioning of the human body.

The human body is both complex in its function and fascinating in its capabilities. There are multiple hormones and proteins and many other things that are working together simultaneously to keep the human body working like a well-oiled machine. Anything that alters or hinders this process will result in the our body responding to the lost function by giving us few signs that will help us recognize where in the body is the problem and how can we fix it. Hormones controls our body’s day to day functions, such as our sleep, temperature, appetite, growth, weight and many more.

The human body consists of eleven major organ systems that maintain homeostasis: the skeletal, muscular, circulatory, nervous, respiratory, digestive, urinary, endocrine, reproductive, integumentary and lymphatic systems. These organ systems are dependent on each other to keep the human body in homeostasis. For example, the nervous and endocrine systems coordinate functions of other body systems because they allow information to be communicated throughout the body. The nervous system consists of the brain, nerves, and spinal cord. It is the fast acting control system because it responds to internal and external changes throughout the body.

The endocrine system and nervous system have many similarities as well as differences. They are the 2 systems responsible for detecting, processing and bringing about responses to ensure the health and achieve to homeostasis for an individual or organism. They regulate many things such as body temperature, water levels, ions and minerals, gases and blood glucose levels. A failure of homeostasis can potentially mean disaster for the organism. For example failure to maintain body temperature leads to hypothermia or heatstroke.

Introduction This essay will reflect on my personal experience, skills, and knowledge gained from my studies and practice of undertaking blood pressure (Bp) whilst completing my professional placement. Bp may be defined as a force of blood against vessel walls in the body, consisting of systolic and diastolic pressure measured in millimeters of mercury. (Waugh and Grant, 2016) Systolic pressure occurs when the hearts left ventricle contracts and forces blood into the aorta causing a heightened atrial pressure, while diastolic pressure refers to complete cardiac diastole, this is when the aortic valve closes and pressure is at its lowest between beats, blood moves into smaller corresponding vessels and the heart rests.

The Basic Facts of High Blood Pressure The heart is a tough operating mechanism which moves blood around the body through a very advanced system called arteries and capillaries; the blood is then carried back to the heart by means of veins. Blood pressure is the thrust of this blood in the body pushing up against the inside walls of the arteries as the heart is pumping. high blood pressure, systolic, diastolic, heart Article Body: The heart is a tough operating mechanism which moves blood around the body through a very advanced system called arteries and capillaries; the blood is then carried back to the heart by means of veins.

The muscular system is very important for everyday life. Without it we wouldn't be able to carry out everyday tasks such as writing this paper or tying our shoes or anything. This system also helps us distribute wastes when our body doesn’t need them anymore, which is important because if the wastes build up the toxins will enter your system the wrong way and it will harm you eventuly. This system interacts with the many other systems but the main two are the nervous system and the digestive system. The nervous system is what controls the brain and the brain tells us to move certain parts of our bodies without us knowing it, this is how our involuntary muscles move.

The endocrine system is such an important system to the body because it functions the bodies use of hormones. The body uses many different hormones and the endocrine system regulates these. When the glands of the endocrine system secrete the hormones, the hormones are put into the bloodstream to be sent to the different parts of the body. The glands that comprise the endocrine system are the hypothalamus, the pituitary gland, and the pineal gland which are all located in the brain, the thyroid, parathyroid, and thymus which are located in the throat, the adrenals and pancreas which are located in the body’s midsection, and the ovaries (female) and testes (male) which are located in the pelvic region. The system is so important because it regulates the body’s metabolism, growth and sexual development, digestion, heart rate, and many of the other body functions regulated by hormones.
