Answer:
Aorta→ Systemic arteries →Body tissue→ Systemic Veins→Vena cava→Right atrium→Right Ventricle→ Pulmonary artery →Lungs →Pulmonary vein→ Left Atrium →Left Ventricle→Aorta
Explanation:
Steps by which blood travels trheough heart from the time it enters the systemic circulation until it returns the systemic circulation.:
- Aorta takes the Oxygenated Blood from the Heart and distributes it to the body tissues throughsystemic arteries.
- The deoxygenated blood from the tissues diffuses out into the capillaries and to the systemic veins.
- Veins join to form the two venacava, the superior vena cava in Inferior vena cava.
- The vena cava pours deoxygenated blood into the Right atrium.
- The deoxygenated blood is pumped into right ventricle through the tricuspid valve.
- The Right ventricle pumps the deoxygenated blood to the lungs throught the pulmonary artery.
- The blood that enters the lung gets oxygenated and is taken up by pulmonary vein .
- The oxygenated blood is then pumped into the left atrium by the pulmonary vein..
- The oxygenated blood from the left atrium is pumped into left ventricle through bicuspid valve.
- The oxygenated blood is then pumped into aorta by the Left ventricle through the aortic valve.
Signals a halt to protein synthesis

Answer:
The hormone responsible for these changes is progesterone, which is manufactured by the corpus luteum. Under the influence of progesterone, the uterus begins to create a highly vascularized bed for a fertilized egg. If a pregnancy occurs, the corpus luteum produces progesterone until about 10 weeks gestation.
It can replace, repair or be a new type of cell to benefit the host.
Cellular differentiation occurs throughout the cell development of a multi-cellular organism. It occurs when the cell changes from a simply zygote into a complex system of tissues and cell types.
<span>Stems cells are cells which have the potential to develop into many different cell types in the body during early life and growth. Stem cells serve as internal repair system in many tissues. When stem cells divide while undergoing cell differentiation, it can either retain being a stem cell or become another type of cell like muscle cell, brain cell, or red blood cell.<span> </span></span>
