About me

Hi! My name is Oli and I'm currently studying medicine at the University of Birmingham.

Having been keen on sciences all throughout school, I'd love to share my passion through tutoring!

After carrying on all of the sciences through to A-level, I have a very good knowledge of each individual science and also how they interact. As my degree suggests, I have a particular interest in biology (not just human!) but I've always loved physics and maths and I really look forward to carrying on my enthusiasm for these subjects through tutoring.

I'm also very keen to provide any medical school admission advice or help with interview technique for medical school applications as it's an extremely stressful time that I've been through myself!

Throughout school I tutored younger students and I also teach during my time at medical school. From this I'm experienced on improving knowledge / understanding and exam technique through methods tailored to each student.

I'll make sure all sessions are enjoyable and, with any luck, I'll be able to pass on, not only my knowledge, but also my passion for these subjects to anyone who is tutored by me!

Don't hesitate to contact me and I'm more than happy to help - I look forward to tutoring with you!

Homeostasis is the process of maintaining a constant internal environment in the body.

An example of this is maintaining the temperature of the body. Human body temperature must be maintained at 37ºC as this is the optimum temperature for human enzymes to work. High temperatures can cause dehydration and eventually death and low temperatures can cause hypothermia and lead to death therefore body temperature must be maintained constant.

The temperature of the body is regulated by the brain. The part of the brain that is involved is called the hypothalamus. It can sense the temperature of the body and then send nerve impulses down to the skin and muscles to increase or decrease heat loss.

There are a few mechanisms that the hypothalamus uses to regulate body temperature:

Firstly, if your body is too hot, sweat glands in the skin secrete sweat onto the surface of the skin. The sweat then evaporates to cause heat loss.

Secondly, the hairs on the body can be moved upright or flat by small muscles in the skin. When upright, the hairs trap warm air to warm the body up and when flat they increase heat loss.

Thirdly, there are blood vessels inside the skin which can swell (dilate) to allow more warm blood to flow nearer the skin surface. This way, heat can be transferred through the skin and away from the body to increase heat loss. Also, the blood vessels can become smaller (constrict) so that less heat is lost if the body is cold.

Lastly, your muscles also receive messages from the brain to tell them to move when cold. This causes shivering which warms the body up.

Through these mechanisms, the body temperature is kept constant, an example of homeostasis.
