The body of your penis is cylindrical in shape and consists of three circular shaped chambers. These chambers are made up of special, spongelike tissue. This tissue contains thousands of large spaces that fill withbloodwhen you are sexually aroused. As the penis fills withblood, it becomes rig...
The heart has four chambers and four valves. The top two chambers (atria) receive blood and the bottom two (ventricles) pump blood out. The valves open to allow blood to flow through and close so that blood can't flow backward. And all of this happens within one heartbeat. Heart ...
Examination of the right chambers of heart, study of role and function of the right ventricle in patients with lung and heart pathologyN. V. TumanskayaA. A. Popovich
Blood must continuously be moved around the body, collecting and supplying vital substances to cells as well as removing waste from them. The heart acts as a pump using a combination ofsystole (contractions)anddiastole (relaxation)of the chambers. The cycle takes place in the following sequence....
The human heart is made up of two upper chambers called the atrium (left and right) and two lower chambers called the ventricles (left and right). In adults right atrium opens to the right ventricle through the tricuspid valve. the wall of the atrium and ventricles are completely close and...
HeartQuestions: 1. What do you notice about the sizes of the four chambers? Annotate the measurements you have recorded onto your drawing. The ventricles are much bigger than the atria and the left ventricle is bigger than the right ventricle. Left atrium wall: 0.4cm Left ventricle wall: 1.4...
The function of the heart's ventricles is to pump blood away from the heart towards the lungs for oxygenation and towards the body for use. What is ventricle and atrium? The atria are thinly lined chambers of the heart towards the top that received blood from the veins of the body. The...

Heart chambers On the inside, the heart is a four-chambered, hollow organ. It is divided into the left and right side by a wall called the septum. The right and left sides of the heart are further divided into two top chambers called the atria (plural of atrium), which receive blood ...
Thetunica intima(also called the tunica interna) is composed of epithelial and connective tissue layers. Lining the tunica intima is the specialized simple squamous epithelium called the endothelium, which is continuous throughout the entire vascular system, including the lining of the chambers of the...
