THE LUNGS The left and right lungs (Figure 23-7a‚ b) are situated in the left and right pleural cavities. Each lung is a blunt cone‚ with the tip‚ or apex‚ pointing superiorly. The apex on each side extends into the base of the neck superior to the first rib. The broad concave inferior portion‚ or base‚ of each lung rests on the superior surface of the diaphragm. Lobes and Surfaces of the Lungs The lungs have distinct lobes separated by deep fissures (Figures 23-7a‚b). The right lung has

The heart is one of the most important organs in your body. So what does it do? It’s function is to pump blood to all the other organs.

The inner layer is called

Coronary arteries supply the heart with a constant supply of blood. These arteries are essential‚ providing oxygen and nutrients that keep the heart constantly pumping. Arteries have three layers including the external layer‚ tunica external‚ middle layer‚ tunica media and the inner layer‚ called the tunica intima. The outer layer is made up of connective tissue with elastic and collagenous fibers. Tunica media is the thickest layer composed of smooth muscle and can change the diameter of the arteries
