Compare to Figure 3.3 – Atria and Ventricles

Figure 3.3

Atria and Ventricles

The heart has two pairs chambers called the Right atrium and ventricles. The functions of the chambers are as follows:

The atriums are located on either side of the heart. Right Atrium is designed to receive the blood that is coming to the heart from the whole body and the Left Atrium is designed to receive the blood that is coming to the heart from the lungs.

The ventricles are also located on either side of the heart. Right Ventricle have thin walls because of a low pump of blood that flows to the lungs which is a short distance xenical cost from the heart. The Left Ventricle has much thicker walls because of a high pressure pump of blood that flows to the rest of the body.

 

Compare to Table 3.1  – Functions of Blood

The cardiovascular system.

Figure 3.1

This slide above is provide from a presentation from share slide (stewart_j, n.d.). It is similar to the table that is shown in the book. NASM deems it important to understand the functions and support mechanisms of blood.

 

Table 3.2  – The Respiratory Pump – The abdominal and thoracic structures that contribute to the expansion and contraction of the lungs.

Muscles of the respiratory pump consist of:

Inhalation: Diaphram, Scalenes, Pec Minor and Sternocleidomastoid.

Exhalaiton: Abdominals and Internal intercostals.

How the respiratory pump works:
