caused by pulsation of subpapillary arteriolar and venous plexuses and is sometimes seen in aortic insufficiency, although it may occur in normal persons under certain conditions. Called alsocapillary pulse(because it was formerly thought to be due to pulsations in the capillaries) andQuincke's ...

the oropharynx is the section behind the mouth, and the laryngopharynx is the area above the larynx. Each part of the pharynx serves as a conduit for air and food, ensuring proper passage to the respective destinations
The cervix, which protrudes into the vagina, is generally 2–3 cm long. The intravaginal portion of the cervix, known as the portio vaginalis, ordinarily is covered with nonkeritinizing squamous epithelium with a number of mucus-secreting glands (Fig. 2). The external os is the...
The gills are the same structure only they’re pushing the blood through capillaries that exchange with water, not air. What most people don’t know is that the gills perform another important function – the excretion of fish waste in the form of ammonia. The gills are the most important ...
Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood. At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs. Carbon dioxide leaves the body when you exhale. Once the blood is ...
What is the function of bronchi in the respiratory system? Name four functions of the respiratory system. What is the function of the trachea in the respiratory system? Briefly explain the following: (a) Respiratory system. (b) Capillaries. Describe the basic structure of the respiratory system...
The carotid body is an extremely vascular organ and receives vascular supply via the internal and external carotid arteries. Two types of capillary beds are responsible for the perfusion of the organ. Type I has capillaries that are large in diameter, fenestrated, and come in close contact with...
The end of the nephron in on itself to form a cuplike structure called glomerular capsule. Within this cup is cluster of capillaries called the glomerulus. The proximal convoluted tubule is next. At the end of the proximal convoluted tubule, there is a U turn called the loop of the ...
