Cardiovascular Sytem :)

• Cardiovascular system?

  The cardiovascular system is responsible for transporting blood, oxygen, and nutrients throughout the body.
• Name all parts of the heart?

  Aorta, Pulmonary Valve, Superior Vena Cava, Pulmonary Veins, Inferior Veins, Bicuspid Valve, Aortic Valve, Left Ventricle, Right Ventricle, Pulmonary Valve, Pulmonary Artery, Tricuspid Valve, Right Atrium, Left Atrium.
• Structure of the cardiovascular system?

  The heart is a large muscular pump and is divided into two halves - right-hand side and the left-hand side.

  The right-hand side of the heart is responsible for pumping deoxygenated blood to the lungs.

  The left-hand side pumps oxygenated blood around the body.

  Each side of the heart consists of an atrium and a ventricle which are two connected chambers.
• Main functions of the heart?

  The atrium is where the blood collects when it enters the heart.

  The ventricles pump the blood out of the heart to the lungs or around the body.

  The septum separates the right-hand side and left-hand side of the heart.

  The tricuspid valve is located between the left atrium and left ventricle and likewise opens due to a build up of pressure, this time in the left atrium.

  The semilunar valves stop the flow of blood into the heart. There is a semilunar valve where the aorta leaves the left ventricle and another where the pulmonary artery leaves the right ventricle.
• what are all of the blood vessels?

  arteries, veins, capillaries
• Functions of the cardiovascular system?

  Transportation of oxygen, nutrients, hormones, and waste products.

  Regulation of body temperature and pH balance.

  Protection against pathogens and blood loss.
• Function of the heart to the lungs?

  Transportation of oxygen and removal of carbon dioxide.
• Blood Pressure?

  The force of blood against the walls of the arteries.
• Systolic Valve?

  Blood pressure while the heart is squeezing.
• Diastolic valve?

  Blood pressure while the heart is relaxing.
• The hearts performance as a pump?

  Cardiac output
• Cardiac output?

  Cardiac output is the amount of blood pumped from the heart every minute nd can be calculated by multiplying heart rate by stroke volume.
• Passage of air into the lungs?

  Air enters the body and is warmed as it travels through the mouth and nose.

  It than enters the trachea.

  The trachea divides out into smaller tubes called the bronchioles. Air travels through the bronchioles.

  At the end of the bronchioles, the air enters one of many millions of alveoli where gaseous exchange takes place.
• What are all the terms of lung volume?

  Tidal volume, Inspiratory reserve volume, Expiratory reserve volume and Residual volume.
• the heart has four chambers, two atria (upper) and two ventricles (lower)
• the heart is located between the lungs
• blood flows from the right side to the left side of the heart through the septum
• Vascular Shunting?

  Heart beats faster.

  Blood vessels narrow.

  Blood sent to the working muscles.

  Blood pressure rises.

  Reflexes and muscle tense to allowing blood to muscle and waste product to be taken away.

  Oxygen levels drop causing build-up of lactic acid and carbon dioxide.

  Blood vessels vasodilate allowing oxygen to working muscles.

  Cause blood pressure to drop.

  Temperature increase.

  Blood vessels to skin to dilate.

  Blood can flow more easily to get rid of the heat.
• What is the role of Platelets?

  To prevent and stop bleeding.
• What is the role of White Blood Cells?

  To fight diseases.
• What is the role of Red Blood Cells?

  Transporting oxygen.
• What is the role of plasma?

  Helps recover injury, removes waste, moves through your circulatory.
• what are the characteristics of the arteries?

  Thick, elastic, muscular, carry oxygenated blood away from the heart.
• What are the characteristics of the veins?

  Thin-walled, carry deoxygenated blood, have valves to prevent backflow.
• What are the characteristics of the capillaries?

  The smallest type of blood vessel. The capillary wall is one cell thick.
• Name all the parts of the heart?

  
• Atria, Ventricles, Septum, Valves, Arteries, Veins, Capillaries.
