During a transfusion, if incompatible antigens are are introduced, antibodies can bind to foreign antigens, causing them to clump together, or: activate. O coagulate. O agglutinate. O granulate.
Anatomy and Physiology of Special Sensory Organs
Sensory organs can be labeled as special sensory structures that permit sight, hearing, odor, and flavor. Sensory structures permitting proprioception, touch, thermal, and pain perception can be classified as more advanced sensory organs. The sensory neurons are trained to find out modifications in the external and internal conditions so that a person's body can react to that change. A stimulus is the first signal that is recognized by any sensory receptor of the body. Stimulus is an impulse generated when there is a change in the surroundings of a person. For example, a heated environment will alert the brain through the thermal sensory organs and generate a reflex accordingly.
Sensory Receptors
The human sensory system is one of the most complex and highly evolved structures, which processes a myriad of incoming messages. This well-coordinated system helps an organism or individual to respond to external stimuli, appropriately. The sensory receptors are an important part of the sensory system. These receptors are specialized epidermal cells that respond to external environmental stimuli. These receptors consist of structural and support cells that form the peripheral unit of the receptor and the neural dendrites which receive and detect the external stimuli.
A blood transfusion is a common medical treatment that involves receiving donated blood through a small tube inserted into a vein in your arm.
A transfusion replaces the component or parts of your blood that you don't have, with red blood cells being the most common. Whole blood, which incorporates all the components, is also available, but whole transfusion is rare.
There are various components in blood, including the following:
- Red blood cells transport oxygen and aid in the removal of waste materials.
- White blood cells assist the body in fighting illnesses.
- Platelets help the blood to clot properly. Plasma is the liquid portion of the blood.
