Transportation in animals

Transportation in animals is a complex process that involves the movement of oxygen, nutrients, and other substances throughout the body. The heart is the main organ responsible for this transportation system. It pumps blood through arteries and veins to deliver oxygen and nutrients to cells throughout the body. The blood consists of red blood cells (RBCs), white blood cells (WBCs), platelets, and plasma. Arteries carry oxygen-rich blood away from the heart while veins carry deoxygenated blood back to it. This process of circulation ensures that all parts of the body are supplied with essential nutrients and oxygen for proper functioning.

Heart

The human heart is an amazing organ that is responsible for pumping blood throughout the body. It consists of four chambers, two atria and two ventricles, which are connected by valves. The heart also contains a network of arteries and veins that carry oxygenated and deoxygenated blood to and from the heart. Blood cells, plasma, and other substances are also circulated through the heart. This article will discuss the structure and function of the human heart in detail.

Blood

Blood is a vital component of the human body, and it is composed of several different types of cells. These include red blood cells (RBCs), white blood cells (WBCs), platelets, and plasma cells. Each type of cell has its own unique role in the body, and they all work together to keep us healthy. 

Red Blood Cells (RBCs) or Erythrocytes 

Red Blood Cells (RBCs) are an essential part of the human body, responsible for carrying oxygen and carbon dioxide throughout the body. RBCs contain a protein called haemoglobin which is responsible for binding and transporting oxygen to the cells. Haemoglobin also binds and transports carbon dioxide away from the cells. Therefore, RBCs play an important role in maintaining homeostasis in the body by ensuring that there is a balance of oxygen and carbon dioxide in the blood stream.RBCs or erythrocytes are responsible for carrying oxygen throughout the body.

White blood cells (WBCs) or Leucocytes 

White blood cells (WBCs) are the main component of our immune system, responsible for fighting off infection and disease. WBCs come in different types and each type has a specific role to play in protecting us from harm. Neutrophils, eosinophils, basophils, monocytes, and lymphocytes are all different types of white blood cells that have their own unique functions. They work together to detect and eliminate foreign invaders that could cause us harm. Understanding the different types of WBCs can help us better understand how our body works to protect us from infection and disease.WBCs or leucocytes help fight off infections.

Platelets

Platelets play an important role in the process of coagulation. They are small cells that are released from the bone marrow and circulate in the bloodstream. They help to form a clot when there is damage to a blood vessel. Platelets contain proteins that bind together when they come into contact with damaged tissue, helping to stop bleeding and form a clot. The platelet's ability to form clots is essential for normal body functioning and helps prevent excessive bleeding, platelets help with blood clotting of cuts and wounds and save blood loss.

Plasma helps transport nutrients throughout the body. Understanding how these different types of cells work together is essential for maintaining good health.

Blood vessels

Blood vessels are the pathways through which blood flows throughout the body. They are made up of three main types of vessels: arteries, veins, and capillaries. 

Arteries

Arteries carry oxygenated blood away from the heart to the rest of the body.The aorta is the largest artery in the body and carries oxygenated blood from the left ventricle of the heart to all parts of the body.The pulmonary artery carries deoxygenated blood from right ventricle to lungs for oxygenation.

Veins

Veins carry deoxygenated blood back to the heart.The vena cava is a large vein that carries deoxygenated blood from all parts of body back to right atrium of heart. Pulmonary veins carry oxygenated blood from lungs back to left atrium of heart.

Capillaries

 Capillaries are tiny vessels that connect arteries and veins and allow exchange of nutrients, gases, and waste products between cells and bloodstream.

The path of circulation in human

The path of circulation in humans is a complex process that involves the heart, lungs, and several other organs. The journey begins with blood being pumped from the heart to the lungs via pulmonary veins. Then, oxygen-rich blood is transported back to the heart through pulmonary arteries. From there, it passes through two ventricles and two auricles before entering the aorta and vena cava respectively. Lastly, valves are used to prevent backflow of blood as it circulates throughout the body.

Blood pressure 

Blood pressure is a vital sign that is closely monitored by doctors and healthcare professionals. It is the force of the blood pushing against the walls of your arteries as it moves through your body. High blood pressure, also known as hypertension, can lead to serious health complications such as stroke and heart attack. In order to measure blood pressure accurately, medical professionals use a stethoscope to listen for the sound of blood flowing through the pulmonary vein and pulmonary artery. The sound is then used to measure the difference in pressure between the ventricles and auricles in your heart, as well as any blockages or abnormalities in your valves or aorta/vena cava. By understanding what normal blood pressure levels are, healthcare providers can detect potential problems early on and take action to prevent them from worsening.
