Today is September 18,2020. I just finished doing my assignments. Our teacher assigned us to do six activities last Monday. Wherein we need to draw the heart of a Chicken, Pig, and Frog. We need to differentiate at least three similarities and two differences of each heart of animals . Second, is to make a concept map on how the blood flows . Third, draw the human heart and give its parts and its function. Fourth, is to answer why are the valves are important in vein. We also need to do a blog regarding our discussion.
And lastly, this activity blog. Here you can see my answers to the activities given to us by our teacher.
SIMILARITIES AND DIFFERENCES
What are the similarities?
They all have right atrium, they all have vena cava which is ultimately responsible for the transport of almost all venous blood (deoxygenated), and lastly they are all meant to pump blood to the body.
What are the differences?
The chicken and pig's heart have an Aorta but the frog's heart doesn't have and also, they have different kind of heart parts, some of them are many but some of them have least.
MAKING A CONCEPT MAP
Base on the concept map, blood enters the heart through two large veins - the superior and inferior vena cava carrying deoxygenated blood from the body into the right atrium.
Blood flows from the right atrium into the right ventricle though tricuspid valve. When the ventricle is full, the tricuspid valve shuts to prevent blood flowing backwards into the atrium.
Blood leaves the heart through the pulmonic valve into the pulmonary artery and flows to the lungs.
The pulmonary vein carries oxygen-rich blood from the lungs into the left atrium.
Blood flows from the left atrium into the left ventricle through the open mitral valve. When the ventricle is full, the mitral valve shuts to prevent blood from flowing backwards into the atrium.
Blood leaves the heart through the aortic valve into the aorta and to the rest of the body.
THE HUMAN HEART AND IT'S FUNCTIONS
Aorta – is the primary corridor that diverts blood from your
heart to the reminder of your body.
Superior Vena Cava - flowing towards the correct chamber of
the heart, returning the oxygenated blood from the body.
Pulmonary Artery - it conveys the oxygenated blood from the
correct ventricle to the lungs.
Pulmonary Vein - conveys oxygenated blood from the lungs
into the left chamber where it is gotten back to fundamental flow.
Right Atrium - the principal office of the heart to get the
oxygenated and carbon dioxide - rich systemic blood from the body.
Left Atrium - the first chamber perceive the oxygenated
blood returning from the lungs.
Pulmonary Valve - opens at the systolic period of the
cardiovascular cycle empowering the deoxygenated blood to be siphoned from the
correct ventricle to the pneumonic flow. It closes at the diastolic period of
the cardiovascular cycle, permitting adequate filling of the correct ventricle.
Mitral Valve - It controls the progression of blood from
your lungs into the left ventricle, the fundamental siphoning chamber.
Tricuspid Valve - manages the progression of blood from your
body into the correct ventricle.
Aortic Valve - plays out a scope of capacities bringing
about the unidirectional progression of blood out of the left ventricle.
Right Ventricle- It gets deoxygenated blood from the correct
chamber and siphons it into the pneumonic flow.
Left Ventricle- gets the now oxygen-rich blood from the
lungs and siphons it into the left ventricle.
Inferior Vena Cava - conveys blood from the lower half of
the body while the unrivaled vena cava conveys blood from the upper portion of
the body.
WHY ARE THE VALVES ARE IMPORTANT IN VEIN?
Valves are important in vein because it keeps the blood moving in the right direction. Valves likewise assist blood with venturing out back to the heart against the power of gravity.
So that's it for today! I hope you learn about the Cardiovascular System. This will help you to know more about hearts and it's functions. Thanks for reading!
