Explaining the role hormones, the essential role of hormones is that of a messenger. Hypothalamus is a branch of forebrain where numerous volume of neurosecretory cells is available. These neurosecretory cells are concentrated in the secretion of a hormone known as neuro hormones. They arouse the anterior lobe of the pituitary to produce various other … Read more
Digestive enzymes work for the breakdown of the polymeric macromolecules to their smaller subunits or building blocks. In animals, they are found in their digestive tracks, and in plants, they are found in the traps, where they help in the digestion of the food. They are also found inside the cells, especially in the lysosomes, … Read more
Introduction Respiration releases energy for life processes to carry on. Aerobic respiration happens in the presence of oxygen, while anaerobic respiration doesn’t require oxygen. Therefore, the human respiratory is specifically designed to enable gaseous exchange. The respiratory tract is the pathway of air from the nose to the lungs and is divided into: Upper Respiratory … Read more
Introduction Respiration is described as the process of releasing energy from food that occurs inside cells. The process requires oxygen intake, which is used to burn food while eliminating waste products (CO2 and water) from the body. This process is of great importance in life because it provides the energy required in all life processes … Read more
Introduction. Respiration volume refers to the gas volume in the lungs at a particular time during the respiratory cycle. The measurement of lung volumes is very integral to the pulmonary function test. An adult male has about six liters of air as the average total lung capacity. Factors such as gender, ethnicity, body composition, and … Read more
It has been made clear that the renin-angiotensin-aldosterone system “RAAS” plays an essential role in regulating the volume of blood and systemic vascular resistance, which together influence cardiac output and arterial pressure. As the name calls, there are three essential components to this system which are renin, angiotensin, and aldosterone. Renin is initially released by … Read more
Kidneys are very essential to our body they help in making red blood cells. They regulate electrolytes (a kind of nutrient) and activate cholecalciferol, too. When your kidneys are damaged, they stop working as they should do. This could happen due to another health condition, like diabetes. A decrease in kidney operation that happens over … Read more
Renal calculi is the medical term used to describe kidney stones, which are small, hard deposits that form in the urine that are made up of mineral and acid salts. Though kidney stones form in the kidneys, they can be transported throughout the urinary tract, which includes the kidneys, ureters, bladder, and urethra. Kidney stones … Read more
Human beings regulate their respiration to suit the immediate needs of the body. The nervous system is responsible for respiration control by using special centers called the respiratory centers of the brain. Respiratory centres of the brain The neuronal signals passed between the respiratory centers of the brain and the diaphragm and muscles in the … Read more
Normal activities of the heart are regulated in an essential way, that’s it is auto regulated by specialized muscles or the nodal tissue, therefore the heart is referred to myogenic. A special neural center in the medulla oblongata can regulate the cardiac function through the autonomic nervous system. Neural signals do increase the number of … Read more
