Why is the heart located very close to the lungs?
So that it can oxygenate the blood before going round the rest of the body
What happens if you only have 2 heart chambers?
If your heart had only two chambers then oxygen-rich blood would be diluted by oxygen-poor blood and your body would not get oxygen as efficiently as it does. Efficient circulation is necessary for mammals such as humans to maintain a high metabolic rate.
Can beta blockers increase heart rate?
Beta 2 is generally associated with smooth muscle relaxation (as in the bronchioles in the lungs) and dilation of blood vessels to skeletal muscles. Beta 1 is responsible for the increase in heart rate. Although beta 2 agonists like Albuterol are meant to trigger only the beta 2 in the lung, you may see a little cross reaction resulting in an increased heart rate. So, in a nut shell...no.
What is a 2 chamber heart?
the 2 chambers of the heart are: 1. atrium 2. ventricle
What is the congenital heart disease in which 2 major arteries of the heart are reversed in position resulting in 2 noncommunicating circulatory systems?
Transposition Of The Great Vessels
Contrast left lung and right lung?
The left lung is slightly smaller than the right lung because 2/3 of the heart is located there. The left lung contains the cardiac notch, an indentation in the lung that surrounds the apex (pointed end) of the heart. The smaller left lung only has 2 lobes, the superior and inferior.
Why is the right lung slightly larger than the left lung?
the left lung is smaller to make room for the heart.. the right lung has 3 lobes and the left lung only has 2 lobes..
Why is the right lung in cattle bigger than the left lung?
well the right lung has 3 lobes and the left lung has only 2. its to give room for your heart.
Why does the right lung have 3 lobes and the left have 2?
The left lung does not have a middle lobe, this makes room for the heart.
Do we have 2 or 4 lungs?
We have 2 lungs, of not equal size. The left lung is smaller than the right lung to give room for your heart.
What membranes are associated with the lungs and the thoracic walls?
the lungs are protected with a db layer serous membrane. 1: is the superficial layer called the Parietal pleura that line the walls of the thoracic cavity. 2: The deeper layer is the visceral pleura, which cover the lungs themselves. In between the both membranes is a small space(cavity)filled with pleurisy to reduce friction.
Is the right or left lung larger?
The right lung is larger than left lung The left lung is made up of 2 lobes while right is made up of 3 lobes.
How many lobes do the right and left lung have?
The right lung contains three lobes. The left lobe only has two. Because of the heart on the left side, the left lung only has two lobes to make more room for the heart to pump on that side.
How many lobes are in the right lung?
The right lung has 3 lobes. This is in contrast to the left lung, which only has 2 in order to make room for the heart, which is located in the left side of the chest cavity.
Why is the heart divided into 2 halves?
Because blood comes in one half and goes out the other. Each half of the heart has a lung pumping oxygen to it.
What can happen from smoking 2 packs a day?
You would be stupid to do that but you will get lung cancer and heart disease and die R.I.P :)
How many parts is the right lung divided into?
the left lung is divided into 2 parts in mammals
