Capillary Vessels

New Website What are capillaries? These are the smallest blood vessels in the body, taking part in micro circulation, by connecting areterioles and venules. {Micro circulation is the network of arterioles, venules and capillaries embedded within organs responsible for blood circulation among tissues} The capillary wall is a one cell layer thick structure, made of… Read More ›

Transport Across Capillary Walls

New Site Substances are transported across the capillary wall in two main methods By diffusion : across receptors, channels By filtration : as a result of Starlings forces Direction and amount of fluid transported by Starlings forces is determined by the hydro static and oncotic pressures on both sides of the capillary walls. Hydrostatic pressure… Read More ›

Formation of Body Fluid

New Blog   Since the net force at the arteriolar end is directed from the capillary towards the interstitial space, blood plasma filters into the surrounding tissue Around 1/200th of blood volume (0.5%) of blood plasma moves alongwith nutrienst, gases, minerals and chemicals {excluding red blood cells amd plasma proteins} In a healthy male adult,… Read More ›

Homeostasis and the Body Systems

New Medical Blog Since all tissues and organs contribute to maintain homeostasis, all organ systems are directly or indirectly playing a role. Nervous system Working as the body’s primary control center, this control the activities of almost every other organ in the body. Autonomous nervous system stimulates/inhibits secretions from the hypothalamus It controls contractions of… Read More ›

Baroreceptor Mechanism

Visit our new website– Arterial blood pressure is normally regulated within a narrow range, with a mean arterial pressure typically ranging from 85 to 100 mmHg in adults. It is important to tightly control this pressure to ensure adequate blood flow to organs throughout the body. This is accomplished by negative feedback systems incorporating… Read More ›

Human Physiology and Homeostasis

Visit our new website– Human physiology is the branch of biological science that explains the specific characteristics and mechanisms of our body that help it to function as a living organism. Homeostasis is the process by which the body maintains its internal environment at optimum conditions to function as a living being Homeostasis: maintenance… Read More ›
