Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve. Human cell video

The blood vessels are the part of the circulatory system that transports blood throughout the human body. There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart.

These are the chemicals that send signals from the axon terminal of one neuron to receptors on the dendrite of another neuron through synapses. Different neurotransmitters have different functions. Here are some examples of neurotransmitters and their functions. Dopamine- responsible for reward-inspired learning. Highly addictive drugs such as cocaine act directly on dopamine receptors. Serotonin- Responsible for regulation of mood, sleep, and appetite Epinepherine- (also known as adrenaline) when secreted raises heart rate, dilates airways, constricts blood vessels and helps in the fight or flight reaction.

Mast cell filled with basophil granules, found in numbers in connective tissue and releasing histamine and other substances during inflammatory and allergic reactions. A mast cell (also known as a mastocyte or a labrocyte) is a type of white blood cell. Specifically, it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems and contains many granules rich in histamine and heparin.

Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development. Fertilization is the event most commonly used to mark the zero point in descriptions of prenatal development of the embryo or fetus. The resultant age is known as fertilization age, fertilizational age, embryonic age, fetal age or (intrauterine) developmental (IUD) age. Human cell video

Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development. The process of fertilization involves a sperm fusing with an ovum. The most common sequence begins with during copulation, follows with ovulation, and finishes with fertilization. Various exceptions to this sequence are possible, including artificial insemination, in vitro fertilization, external without copulation, or copulation shortly after ovulation. Human cell video

He cell (from Latin cella, meaning small room[1]) is the basic structural, functional, and biological unit of all known living organisms. Cells are the smallest unit of life that can replicate independently, and are often called the building blocks of life. The study of cells is called cell biology. Human cell video

The cell membrane (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins. Cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, glycocalyx, and intracellular cytoskeleton. Cell membranes can be artificially reassembled. Human cell video

There are two bean shaped kidneys in the human body. A normal kidney is about 2. 5 cm thick, 10 cm long and 5 cm wide. They are reddish-brown in color and each weighs approximately 130 gm in adults. Both kidneys receive blood from the renal artery; in a resting adult approximately 1. 2 to 1. 4 Litres of blood flows through both kidneys in one minute which means every 4 to 5 minutes all the circulating blood in the body passes through the kidneys. Kidneys help remove excess salt, water and waste products from the bloodstream. Like other endocrine organs, kidneys also secrete important hormones such as rennin and erythropoietin into the circulation. These hormones play significant roles in the production of blood cell and in the regulation of blood pressure. Human cell video
