Given alongside is a diagram of the human heart showing its internal structure. Label the parts marked 1 to 6, and answer the following questions. Which chamber of the heart receives deoxygenated blood from the body? View Solution Fishes have venous heart. The heart receives deoxygen-ated blood...
Vertebrate hearts can be classified based on the number of chambers present. For instance, most fish have two chambers, and reptiles and amphibians have three chambers. Avian and mammalian hearts consists of four chambers. Humans are mammals; hence, we have four chambers, namely: Left atrium Rig...
Heart, organ that serves as a pump to circulate the blood. It may be as simple as a straight tube, as in spiders and annelid worms, or as complex as the four-chambered double pump that is the center of the circulatory system in humans, other mammals, and
The smallest heart is less than a 10th of an inch in total length and is found in a small species of insect. Is a human heart two-chambered? Humans do not have a two-chambered heart. Humans have a four-chambered heart with two atria and two ventricles. All mammals have four-chambered...

What is the purpose of heart valves?Heart:The heart is the main organ of the circulatory system or cardiovascular system. The heart is a muscular organ that is present in most animals, pumps blood through the circulatory system. In mammals and birds, the heart has 4 chambers: ...
The muscle bands are also much shorter in diameter than those of mammals, leading to a much higher number of cells per unit volume within the organ. Avian myocardial cells also lack transverse tubules (T tubules), and instead use junctional processes as “couplings” between the sarcoplasmic ...
