What else can I help you with?
what cavity is on The medial surface of the left lung that accommodates the contents of the media-stinum?
The cavity on the medial surface of the left lung that accommodates the contents of the mediastinum is known as the cardiac notch. This indentation allows space for the heart, which is located slightly to the left of the midline in the thoracic cavity. The cardiac notch is a prominent feature that distinguishes the left lung from the right lung, which does not have a similar indentation.
The heart is medial to the lung?
yes it is
Is the heart medial or lateral to left lung?
Yes, the heart is medial to the ribs. The ribs are lateral to the heart.
Why does the left lung have a notch at its inferior medial end?
The left lung has a cardiac notch at its inferior medial end to accommodate the position of the heart. This notch allows space for the heart to fit into the left lung, preventing compression of the heart by the lung during breathing movements.
What is the insertion of the primary muscle used during a lung?
medial surface of the tibia
Which organ makes a concave impression on the medial side of the left lung?
heart
Large tube to each lung?
It is called the Bronchus
What membrane or sac that encloses each lung is a?
The lung is enclosed by a thin memrane called pleura
The tubes into which the trachrea divide to go into each lung?
the left and right bronchi
What is the top of the lung called?
The top of the lung is called the apex. It is the highest point of each lung, located just above the clavicle and extending into the root of the neck. The apex plays a role in the overall function of the lung, allowing for the expansion and contraction needed for breathing.
Describe the pleural coverings of the lung and explain their purpose?
Each lung is suspended in its own pleural cavity and rests on the muscular diaphragm. The medial surface has a hilus (indentation) where the bronchi enter. Because of the shape and location of the heart, the lungs differ in size and shape. The left lung is smaller with 2 lobes, the right has 3 lobes. Lungs are mostly air spaces and connective tissue. The lung contains the air sacs where oxygen diffuses from air sacs into the blood vessels and waste carbon dioxide diffuses from the blood vessels into the air sacs. Each lung exists in a pleural cavity, a serous membrane compartment which prevents friction damage as the lungs expand and contract during breathing. The visceral pleura is the membrane fused to the outer surface of the lung; the parietal pleura is the membrane which lines the body wall. Between the two membranes in the pleural fluid.

How many bronchioles do you have in each lung?
There are about 30,000 of them in each lung.
