Biology

Fats

________ break down using insulin into fatty acids and glycerol.

Egestion

________ is when undigested food leaves your body as faeces.

oviduct

The ________ carries the ovum from the ovary to the uterus and this is where the sperm meets the ovum, and the ovum is fertilized here.

trachea

You have a(n) ________, which is the pipe connecting to the nose and the mouth and where oxygen goes.

Starch

________ is too big to be absorbed so it has to be digested, and it is digested into sugars (glucose)

amniotic fluid

The baby is surrounded by ________ which provides protection and cushioning for the baby.

carbon dioxide

In your lungs, oxygen from the air diffuses into your blood, and at the same time, ________ and water, which are waste products of respiration, are breathed out into the air.

cervix

The ________ is a part separating the uterus and the vagina.

scrotum

The ________ is a sack of skin that holds the testes, and the testes make sperm continuously after puberty.

Proteins

________ get digested into amino acids, which are ordered differently depending on what cell they are going to or going to be created as.

Calcium

________ is important for making up bones and your teeth, and iron is important for making red blood cells.

Veins

________ have valves which stop the blood going the wrong direction and causing complications.

Circulation

________ is the transport of blood (which carries glucose and oxygen) around the body.

gas exchange

Capillaries are tiny tubes which are extremely thin, making them really productive for ________ as they can go in and out really easily.

puberty

After ________ starts for a woman, every month (or 28 days) an egg or ovum is released from the ovary.

vagina

The sperm is designed to swim from the ________ to the oviduct.

DNA

The egg and the sperm contain 50 % of the ________ needed to make a human, and together they make 100 % of a human.

Arteries

________ do not have them as the blood flow is strong enough to make the blood constantly flow correctly.

uterus

The ________ is sometimes called the womb.

Kwashiorkor

________ is a disease that is caused by a lack of proteins.

Diffusion

________ is the movement of substances from high to low concentrations.

sperm

The ________ is small and has no food storage.

Digestion

________ is the breaking down of large, insoluble food molecules into small, soluble ones by the body for absorption.

sugary carbohydrates

There are some nutrients you can absorb without digesting them, as they are small enough, such as vitamins, minerals and ________.

urethra

The ________ is where both sperm and pee come out from.

Valves

________ open when blood is flowing in the right direction, and the ________ shut if the blood tries to flow in the opposite direction.

Aerobic respiration

________ is a chemical reaction that happens in your cells.

placenta

The ________ has a large surface area.

Fertilization

________ happens in the oviduct which is where the sperm meets the egg.

male sex cell

The ________ is called sperm.

Capillaries

________ also have a wall that is one cell thick, which makes gas exchange very easy as gasses can pass by really easily.

Oxygen

________ diffuses from the lungs, which has a high concentration, to your blood, which has a low concentration.

Alveoli

________ are spongy and have a large surface area.

digestive journey

The ________ begins in the mouth and goes down the oesophagus (gullet) where muscles push the food down.

female sex cell

sperm duct

The ________ is a pipe connected to the testes and the urethra.

cervix

The ________ is the opening, or the ‘ neck, of the uterus and it is on top of the vagina.

vagina

The ________ connects the cervix to the outside of the body and the sperm is deposited here during sex.

uterus

The ________ is where the foetus is made and held.

oviduct

The ________ is where the sperm and the ovum meet.

Proteins

________ are especially important when we are growing as they make new cells.

Fats

________ are very similar to carbohydrates; however, they are less healthy and having too many fats can cause obesity.

carbon dioxide

In addition, phenol red is a(n) ________ indicator, going from red /orange to yellow.

vagina

The ________ meets the penis and that is where the sperm is inserted.
