Single Circulatory System

Fish have a single circulatory system in which blood passes once around the body before returning to a two-chambered heart.

BUT...

In birds and mammals, there is a double circulatorysystem – the lung or pulmonary circuit and the body or systemic circuit.

Blood is first pumped from the heart to the lungs and back to the heart, before being pumped to the remainder of the body and back.

The heart is therefore a double pump and is divided into two halves.

♠ Study Tips

Early Morning hours is the best time to study as you wake up refreshed away from all sorts of disturbances. The ions in the environment is said to be lower in the early mornings hours (3 am - 6 am ) which makes the morning hours the best time to study more things in the least possible time. Here are 3 other reasons why morning hours is the best to study.

1.You wake up refreshed - Early in the morning you wake up refreshed and stays clear headed. I advise this based on my experience as I was able to learn any amount of topics in the morning compared to evening hours.

2.Helps better memory - After sleep, processing and learning is said to improve based on recent studies. Revising your lessons early morning helps to remember the contents on a specific topic better.

3.Helps better focusing - There will be very less distractions in the morning compared to any other time of the day and a focused learning is possible in the morning.
_______________________________

The ideal time of morning hours of 3 am - 6 am is said to be the best time. A half an hour nap afterward will help you to better refresh your mind. Avoid learning for more than 3 hours in a stretch and take some short breaks of 10 minutes in between your study time.
